Is using eyeliner regularly good for the eyes?

since high school i kept on using this thing.. because i'm some kind of a "emo" way back in teenager.. and besides i idolize avril lavigne.. and still now, i kept on wearing eyeliner not for fashion but because i get used to it.. i can't go outside the house without it.. now, i wonder if it is good and healthy for the eyes to use eyeliner regularly.. i need answers please?
